4.8. Screen Clock
If you want to know what time it is or if someone has called you or messaged you
without opening or waking up the screen, Screen Clock is an amazing function that
can assist you. This will display the time and reminders like missed calls, unread
SMS, unread Wechat, and QQ messages even when the screen is off.
To Enable Screen Clock:
1. Go to [Settings] > [Display & Brightness] > [Screen Clock] and switch Screen
Clock to green to enable.
